It is due to updating of system.This thing happens generally when phone doesn't support or have effect of update.First you should try to reset your phone.May be it solve issue.Factory reset sometime solve even big problems.To do factory reset first open menu application.Then will see settings.Touch to open settings.when it open drag to below there will see Privacy as an option denoted.Tap on privacy & below will see personal Data.There you find Factory Data Reset.Tap on that & phone will be asking for an option like On Or Cancel.Tap on Ok your phone will be reset.To reset the phone,it will take sometime.Now once done again restart your phone.Then check the issue,if gone then good otherwise use previous version.
